NAME

        xanalogtv - Simulate reception on an old analog TV set
 

SYNOPSIS

        xanalogtv  [-display  host:display.screen] [-window] [-root] [-install]
        [-visual visual] [-cycle] [-no-cycle] [-fps]
 

DESCRIPTION

        xanalogtv shows a simulation of an old TV set showing test patterns and
        any  other  images  you have provided. It reproduces a wide range of TV
        reception bummage: snow, bloom, ghosting, and loss of vertical and hor-
        izontal  sync.  It  also  simulates  the  TV  warming up. It will cycle
        through 12 channels, some with images you give it, and some with  color
        bars or nothing but static.
 
        The  images that it uses will be grabbed from the portion of the screen
        underlying the window, or from the system's video input, or from a ran-
        dom  file  on  disk,  as  indicated by the grabDesktopImages, grabVide-
        oFrames, and chooseRandomImages options in  the  ~/.xscreensaver  file;
        see  xscreensaver-demo(1)  for more details. It looks best with a video
        input or your digital photo collection.
